Biorąc pod uwagę trzy wartości liczbowe - będące elementami koloru czerwonego, zielonego i niebieskiego (osiem bitów na kanał, od 0 do 255) - program musi wypisać nazwę danego koloru.

Na przykład;

Input:  255, 0, 0  
Output: Red

lub;

Input:  80, 0, 0
Output: Dark Red

Jest to konkurs popularności, więc niezależnie od odpowiedzi, która uzyska najwięcej głosów do pierwszego lipca, wygrywa.

Inspirowane przez: Pokaż wejściowy kolor RGB

Pyton

Jest to skrypt w języku Python, który wykorzystuje wyniki badania kolorów xkcd , w którym Randall Munroe zadał tysiącom ludzi dokładnie to samo pytanie. Dotarł do następującej tabeli:

Ankieta zawiera tylko dane o w pełni nasyconych kolorach (wydaje mi się, że kolory nienasycone zostałyby opisane jako „szarawe”). Oznacza to, że musimy wykonać kilka sztuczek związanych z kolorem, aby zmusić nasz wkład do pełnego nasycenia.

To, co zrobiłem tutaj, to po prostu konwersja koloru wejściowego na HSV, zwiększenie nasycenia i nazwanie go dniem. Prawdopodobnie nie jest to bardzo poprawne z punktu widzenia postrzegania kolorów, ale tutaj działa wystarczająco dobrze - i jest na tyle proste, że potrzebujesz tylko standardowej biblioteki. Akumulatory rzeczywiście włączone.

Skrypt oczekuje, że plik satfaces.txt, stąd ( lustro ), będzie w bieżącym katalogu.

import sys, colorsys

n = (int(sys.argv[1], 16))
r = ((n & 0xff0000) >> 16) / 255.0
g = ((n & 0x00ff00) >> 8) / 255.0
b = ((n & 0x0000ff)) / 255.0

(h, s, v) = colorsys.rgb_to_hsv(r, g, b)
(r, g, b) = colorsys.hsv_to_rgb(h, 1, v)

match = "[{}, {}, {}]".format(int(r*255), int(g*255), int(b*255))

for line in open("satfaces.txt"):
    if line.startswith(match):
        print("You were thinking of: " + line.split("] ")[1].strip())
        break

Niektóre przykłady działają:

Powiedziałbym, że to całkiem blisko.

Zaktualizuj za pomocą GUI!

Pobieram listę kolorów z tej strony Wikipedii (i powiązanych stron).

Dołączyłem również trochę NLG, aby uzyskać wyniki, takie jak „bułgarska róża z nieco mniejszą ilością zieleni i niebieskiego” i niektóre jej warianty. Spróbuj zagrać razem, aby dowiedzieć się, czy potrafisz odgadnąć prawdziwą „bułgarską różę”, korzystając z tych informacji zwrotnych. :)

Algorytm spróbuje znaleźć kolor, który jest najbliżej wejścia, zgodnie z odległością euklidesową. Możesz więc wprowadzić dowolną trójkę liczb, a to da kolor najbliższy tej trójce.

(kod akceptuje wartości „rozdzielone przecinkami”, „rozdzielone spacjami” lub „rozdzielone przecinkami”)

Ostrzeżenie

Ten kod łączy się z Wikipedią, więc wymaga połączenia z Internetem, aby uruchomić się za pierwszym razem (i zapisać informacje w pliku w tym samym słowniku). Jednak kolejne czasy będą czytać z pliku. Jeśli chcesz mieć wersję offline, kod jest dostępny pod tym linkiem Ideone (z próbnym uruchomieniem).

JavaScript

Z myślą o użytkownikach psów napisano następującą funkcję:

function getColorName(r, g, b) {
    return "gray";
}

Dla bardziej wyrafinowanych psów:

function getColorName(r, g, b) {
    var gray = (0.21*r + 0.71*g + 0.07*b);
    if (gray < 64)
        return "black";
    else if (gray < 128)
        return "dark gray";
    else if (gray < 192)
        return "light gray";
    else if (gray < 256)
        return "white";
    else
        whimper();
}

Matematyka

Aktualizacja: Dodano parametr do ustawiania liczby najbliższych kolorów do wyświetlenia. Domyślnie jest to 5 kolorów.

Biorąc pod uwagę wartości RGB koloru bez nazwy, poniżej znajduje się nnajbliższe kolory z listy 140 nazw kolorów HTML. Następnie drukuje nienazwany kolor i 5 najbliższych sąsiadów na 3-przestrzeni, z osiami dla koloru czerwonego, zielonego i niebieskiego. W etykiecie wydruku podaje nazwę najbliższego koloru i podaje jego wartości RGB.

colorInterpret[rgb_,n_: 5]:=
Module[{colorData,valsRGB,pts,closest},
colorData=({ColorData["HTML",#],#}&/@ColorData["HTML","Range"][[1]])/.{RGBColor[x__]:> {x}};
valsRGB=colorData[[All,1]];
pts=Append[colorData[[Position[valsRGB,#]&/@Nearest[valsRGB,rgb,n]//Flatten]],{rgb,"Unnamed Color"}];
closest=pts[[1]];
Graphics3D[{PointSize[.05],
{RGBColor@@#,Point[#],Text[Style[#2,Black,14],(#-{.01,.01,.01})]}&@@@pts

R

R ma osadzoną listę 657 nazw kolorów do celów drukowania. Poniższy kod pobiera dane wejściowe od użytkownika i oblicza odległość między tym wejściem rgb a wartością rgb tych 657 kolorów i wyświetla nazwę najbliższego.

a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))

Nie golfowany:

a <- as.integer(strsplit(readline(),", ")[[1]]) #Ask user input as stdin, and process it
color_list <- sapply(colors(),col2rgb) #Convert the color name list into an RGB matrix
#Computes the difference with user input, adds the absolute value and output the name of the element with the minimal value
names(which.min(colSums(abs(apply(color_list, 2, function(x)x-a)))))

Przykłady:

> a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))

Edycja: Ten sam pomysł, ale przy użyciu listy nazw z colorHexa :

a=strsplit(xpathSApply(htmlParse("http://www.colorhexa.com/color-names"),"//li",xmlValue),"#")
n=sapply(a,`[`,1)
r=apply(do.call(rbind,strsplit(sapply(a,`[`,2)," "))[,2:4],2,as.integer)
n[which.min(colSums(abs(apply(r,1,`-`,as.integer(strsplit(readline(),", ")[[1]])))))]

Przykład:

> a=strsplit(xpathSApply(htmlParse("http://www.colorhexa.com/color-names"),"//li",xmlValue),"#")
> n=sapply(a,`[`,1)
> r=apply(do.call(rbind,strsplit(sapply(a,`[`,2)," "))[,2:4],2,as.integer)
> n[which.min(colSums(abs(apply(r,1,`-`,as.integer(strsplit(readline(),", ")[[1]])))))]

color := Color r: 255 g: 0 b: 0 range: 255.
colorNames := Color registeredColorNames copyWithout: #transparent.
nearestColorName := colorNames detectMin: [ :each | (Color named: each) diff: color].

Wyniki są mieszanej jakości. Wszystkie ciemniejsze kolory są nazywane szarymi , ciemnoszarymi lub bardzo ciemnoszarymi . Prawdopodobnie Colorjest diff:metoda może być lepiej.

Dla bardzo prosty wizualizacji zrobić :

Odnosi się to do kolorów X11 z rgb.txt. Na moim Ubuntu jest, /etc/X11/rgb.txtchoć wiem, że na niektórych systemach jest /usr/lib/X11/rgb.txt. Google rgb.txti pobierz go, jeśli nie korzystasz z X11.
